CLI/TUI multi-file apply_patch approval only shows first file diff

[german-swan]

Description

In CLI/TUI mode, when an agent uses apply_patch with changes across multiple files, the approval/review UI only displays one file's diff instead of rendering every changed file.

apply_patch already returns structured per-file diff metadata, but the permission UI still renders the request as a single edit diff blob.

Steps to reproduce

1. Start an interactive CLI/TUI session.
2. Ask the agent to use apply_patch on 2 or more files in one patch.
3. Wait for the edit permission/approval prompt.
4. Inspect the rendered diff.

Expected behavior

The approval UI shows a separate diff block for each changed file in the patch.

Actual behavior

Only one file's diff is displayed, even though the patch touches multiple files.

Likely cause

• packages/opencode/src/tool/apply_patch.ts already populates metadata.files for each changed file.
• packages/opencode/src/cli/cmd/tui/routes/session/permission.tsx handles edit permissions by reading only metadata.diff / metadata.filepath, so multi-file apply_patch requests are rendered as a single diff view instead of iterating metadata.files.
• There is already a multi-file renderer for completed apply_patch results in packages/opencode/src/cli/cmd/tui/routes/session/index.tsx, which suggests the permission path is the missing piece.
• packages/opencode/src/cli/cmd/run.ts also appears to lack explicit apply_patch handling, so non-interactive CLI output falls back to generic tool rendering.

Suggested fix

• In packages/opencode/src/cli/cmd/tui/routes/session/permission.tsx, render request.metadata.files when present, with a per-file diff block and fallback to the existing single-file edit behavior.
• In packages/opencode/src/cli/cmd/run.ts, add explicit apply_patch rendering that uses metadata.files when available.

[mode89]

Having the same issue. When it presents a multi-file edit, it shows diff only of the first file. Once pressed "Allow once", it applies edits to all files and only then shows diffs of the remaining files.

I asked my Claude Code (with Opus 4.6) to analyze the current code of OpenCode. It said that it is supposed to let you approve each file one at a time. Then it went ahead and researched OpenTUI's code and said that issue might be that the useKeyboard hook in opentui has no debouncing or event deduplication.
